Major Mackenzie has east & west designations because it's in Richmond Hill. You need the directions to tell the difference between an address at Yonge & Trench and one at Yonge & Newkirk, since they're both in the same city.
But if the numbers run east and west from Yonge it would make sense to have east-west sections just to standardize things in a contiguous urban area where Yonge is still the general divider. After all, addresses on the major north-south streets don't start at "1" again at Steeles.
It's kind of the same thing with Davis Dr. When the name was extended west along former Hwy. 9, it was given a "west" designation, but the existing section east of Yonge didn't have an "east" added to match it. Clark Ave. does the same.
